City Nature

Just around the corner were I live is a fallen tree at the border of the small city park.
On that tree, that is there already for some years, grow all kind of mushrooms.

I think this is the Pholiota mutabilis, or in Dutch Stobbezwammetje. This is a fungus that grows on dead hardwood.

I'm always surprised about the variety of nature you can even find within the city.
